Abstract

This invention discloses a phosphorescent OLED. The light emitting layer thereof comprises a phosphorescent host material, an exiton blocking material, and a phosphorescent dopant. The invention obviates the use of a hole blocking layer while substentially preventing holes diffusion to the electron transport layer.
